Review each palace at spaced intervals
Walk your palace at 1 day, 3 days, and 1 week after encoding — then less frequently.
Key takeaways
- What it is: Walk your palace at 1 day, 3 days, and 1 week after encoding — then less frequently.
- Why it works: Like any memory, loci associations weaken over time if not reactivated. Spaced retrieval walks leverage the spacing effect: reactivating a memory just before it fades substantially slows further forgetting. Each successful palace walk also strengthens the scene-to-item association, eventually making retrieval automatic enough to be useful under real-world conditions.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Walking the palace once after encoding and then not returning to it — without spaced review, the associations decay rapidly and the palace fails to deliver long-term recall.
Why it works
Like any memory, loci associations weaken over time if not reactivated. Spaced retrieval walks leverage the spacing effect: reactivating a memory just before it fades substantially slows further forgetting. Each successful palace walk also strengthens the scene-to-item association, eventually making retrieval automatic enough to be useful under real-world conditions.
How to do it
- 1After encoding a palace, schedule the first review walk 24 hours later.
- 2Complete the review without peeking — any item you cannot retrieve gets its scene rebuilt.
- 3Space subsequent reviews: 3 days, then 1 week, then 2 weeks, adjusting based on accuracy.
- 4Items you can retrieve without effort can be spaced further; items you miss return to a shorter interval.
What the evidence says
RCT / meta-analysisSpaced practice improves long-term retention in virtually every tested domain, and there is no reason to believe loci associations are exempt. The spacing effect is among the most replicated results in memory research.
Honest caveat: The specific spacing schedule above is a heuristic; optimal intervals depend on how long you need to retain the material and how well the initial encoding went.

Common mistake
Walking the palace once after encoding and then not returning to it — without spaced review, the associations decay rapidly and the palace fails to deliver long-term recall.
IX Coach schedules your palace review walks at algorithmically determined intervals based on how accurately you retrieved each locus during the previous walk, rather than relying on your own judgment of when to review.
